Watt-hour (Wh) is a unit of energy.

1 watt-hour is the energy that is consumed by power consumption of 1 watt during time period of 1 hour:

1 Wh = 1W x 1hr

1000 watt-hour are equal to 1 kilowatt-hour:

1000 Wh = 1 kWh

A Watt-hour (Wh) is a unit of energy equal to one watt of power consumed for one hour. A kilowatt-hour (kWh) is a unit of energy commonly used by utilities to measure electricity consumption, equivalent to 1,000 watt-hours.

The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. An energy expenditure of 1 Wh represents 3600 joules (3.600 x 103 J). To obtain joules when watt-hours are known, multiply by 3.600 x 103. To obtain watt-hours when joules are known, multiply by 2.778 x 10-4. In general, energy (E) is equivalent to power (P) multiplied by time (t). To determine E in watt-hours, P must be expressed in watts and t must be expressed in hours. Suppose a 60-W bulb burns for 3 h. Then P = 60 and t = 3, so the energy E in watt-hours is: E = Pt = 60 x 3 = 180 Wh If P and t are not specified in watts and hours respectively, then they must be converted to those units before determining E in watt-hours. from wikianswers

1 kW hr or 1 kilowatt hour is one thousand watts used for one hour. It is the unit that electric utility companies use to bill costumers. For example; you turn on ten 100 watt light bulbs, that is 1000 watts, leave them on for one hour and that is one kW hr. If your electric utility company charges $0.20/kW hr burning those ten bulbs cost you $0.20.

A kilowatt hour is 1000 watt hours.

Answer

A watt hour is the amount of energy consumed, over a period of one hour, at the rate of one watt. The rate of consumption of energy being 'power'.

How do electric companies make money?

Electric companies make money primarily through the sale of electricity to consumers. They generate revenue by charging for the amount of electricity used, often measured in kilowatt-hours. Additionally, they may earn income from service fees, maintenance charges, and selling excess power to other utilities or grid operators.

How are electricity and related?

Electrical energy is a form of energy, and can be measured in the same units, Joules in the SI system. Note that 1 watt = 1 Joule/sec. Electrical energy is often expressed in Kilowatthours or Megawatthours, which are the normal ways an electric company measures your usage. 1 Kilowatthour just means a steady power of 1 kilowatt maintained for 1 hour. Since there are 3600 seconds in an hour, 1 kilowatthour = 3600 kilowattseconds. Now 1 watt = 1 Joule/sec, so 1 Joule = 1 wattsec, 1000 joules = 1 kilowattsec, so 3600 kilowattsecs = 1000 x 3600 Joules = 3.6 x 106 Joules = 1 kilowatthour.
